The document discusses using digital manipulatives (DMs) for experimental design in the classroom. It recommends ensuring software is updated and exploring DMs that allow variable manipulation. Participants are asked to evaluate three DMs for their usefulness in experimental design by exploring affordances and limitations. The document then guides exploring a DM on projectile motion and dividing into teams to design experiments using DMs in shared documents. Resources for additional DMs are also shared.
